Abstract:
The invention relates to a method for manufacturing dielectric ceramic powder and a multilayer ceramic capacitor using the ceramic powder. According to the invention, BaCO3 powder is dispersed into a solution of solvent and dispersant to prepare BaCO3 slurry and then the resultant BaCO3 slurry is wet-milled. Also, TiO2 powder slurry is mixed into the wet-milled BaCO3 slurry to form mixed slurry and then the mixed slurry is dried into mixed powder. Finally, the dried mixed powder is calcined to produce BaTiO3 powder.
